The LG LJ5500 is an entry-level 1080p smart TV which features LG's WebOS platform. It has a relatively wide viewing angle, making it better than average for use in a wider living room. Unfortunately, its picture quality leaves a lot to be desired, and its 1080p resolution is a bit antiquated. It is the same TV as the LJ550M found at BestBuy and the LJ5000 and LG500M are variants without smart features.
Poor TV for a mixed usage. The LG LJ5500's shortcomings stack up well above its positives, and its below average picture quality greatly reduces its capabilities with every usage.
Not a good TV for watching movies in dark room. The LJ5500's blacks are shallow and very cloudy making them quite distracting, and its 1080p resolution means it cannot fully take advantage of modern content.
Average TV for watching cable or broadcast television. The LJ5500 gets bright enough for most rooms, and it handles reflections decently. Its WebOS smart features also make it easy to access content. Unfortunately, static content such as network logos are retained for a few minutes, and the overall picture quality is subpar.
The LJ5500 does a decent job with sports broadcasts. Its wide viewing angle means watching it from the sides won't affect the picture quality too much, and it handles fast motion quite well. Unfortunately, its uniformity could be better, and static on-screen content can sometimes be retained for a few minutes.
Passable TV for gaming. The LJ5500 has low motion blur, so fast motion doesn't have any distracting trails. Its input lag is also fairly low, which keeps games responsive and immersive. Unfortunately, the TV's poor overall picture quality reduces the quality of the experience.
The LJ5500 does not support HDR.
The LJ5500 does not support HDR.
Mediocre TV to use as a PC monitor. While it is capable of 4:4:4 chroma and has no major issues with viewing angles, its 1080p resolution is less than ideal for productivity and its input lag could be better. It also lacks niche features like a 120hz input.
The design of the LJ5500 is basic and similar to most other LG TVs is the 6 series such as the UJ6300. It won't stand out in a room but is functional with quite easy to access inputs and has a wide stand that supports the TV well.
Similar to most other LG TVs, the LJ5500 has a stand almost as wide as the TV. It is made of plastic but does support the TV well.
Footprint of the 43" TV stand: 7.3" x 33.4"
The LJ5500 has a simple plastic back. It does look a bit better than most low-mid range TVs due to the molded plastic. Most of the inputs are out the side of the TV and so easy to access if placed close to a wall, but legacy inputs may be difficult to connect when wall mounted.
The borders of the TV have an average thickness, but look quite good due to the smooth plastic.
The TV appears quite thick when viewed from an angle but this isn't too much of an issue. It will stick out slightly if wall mounted.
The front of the TV stays fairly cool, and the back only gets warm to the touch in a few spots, the warmest being near where the power cord plugs into the TV.
The build quality is decent. Everything is made of plastic but fits together quite well without too much play. It is not likely to be an issue with normal use.
The LJ5500 has a sub-par native contrast ratio for an LED TV. When compared to other IPS TVs though, with a contrast ratio of 1140, it is in the middle of the pack for this type of panel.
This low contrast ratio means that when set in a dark room, the blacks won't be very black, but will look more like gray than really black. Fortunately, this is less noticeable when the TV is set in a room with a good lighting since the room ambiant light will render less noticeable this low contrast ratio.
The LJ5500 does not have a local dimming feature. The video is for reference only.
Decent SDR peak brightness, good enough for a moderately lit room but may appear too dim in a bright room. The brightness remains consistent no matter the content shown, which is good.
HDR is not supported.
The LJ5500 overall gray uniformity is average. Looking at our 50% gray uniformity picture, the main thing that catches the eyes is the 2 brighter spots in the top left part of the screen. The corners and sides are also a bit darker than the rest of the screen and the bottom part is a bit warmer than the top. Dirty screen effect is visible, unfortunately, especially while watching sports like hockey of soccer.
The uniformity in the darker shade of gray is much better than the 5 percent though, and not much can be noticed at all on that aspect.
Mediocre viewing angle, even for a TV with an IPS panel, but better than almost all TVs with VA panels. Brightness decreases and colors shift when the TV is viewed from a small angle, but the black level remains very consistent which is good.
The LJ5500's black uniformity is bad. Some flashlighting is visible near both top corners. Some clouding was also visible here and there with some darker patches near the lower corners. Overall, the screen is not very uniform and this will be particularly visible in dark scenes in movies or TV shows.
The reflection handling of the LJ5500 is quite good. It has a semi-gloss finish which diffuses direct reflections across the screen, reducing their intensity. It is fine for an average room, but in a bright room, reflections may be an issue.
Out of the box, when the LG LJ5500 is set to the 'Expert (Dark room)' picture setting, and with the 'Warm2' color temperature, the overall accuracy is below average. If the TV is set to another picture mode or one of the other color temperature, then the accuracy is even more disappointing.
The white balance is a bit on the warmer side, but just slightly, and the dE is higher than what we would like (4.16), as an avid enthusiast could notice there is something a bit off here. The gamma is not too bad though since even if the curve is not flat, we still end up with 2.22, which is not too far from our target. The only small issue with the gamma is in the lower stimulus level, where the TV might loose some contrast in the very dark region, but besides that, it looks good.
The color accuracy is also a bit high with a dE of 3.91. Most of the issues here derive from the fact that the white point is a bit off and thus, all the other colors follow. Only the yellow and blue are a bit more off target than the rest.
After calibration, the LJ5500 shows excellent accuracy. Both the white balance dE and color dE are much more precise and accurate. There is only a small imperfection in the lower stimulus, but this did cause a problem and we could not fix it without causing more trouble.
The only downside here is that the whole process was pretty inconsistent, as the 2 point, 20 points white balance and color space management were not very accurate and responsive. In the 20 points white balance control, each point was affecting up to 2 or 3 points higher, make the whole process a bit longer. This was a bit of a surprise, as much of the 2017 LG line up that we did calibrate had very responsive and precise control over the white balance.
In the end, the calibration was still a plus and the result was good, but it only took a bit more time to do than usual.

Upscaling of low-quality content such as DVDs is quite good. The image is a bit softer than usual, but edges remain defined.
720p content such as cable is upscaled well. Unlike most other LG TVs, very few halo artifacts are visible along edges which is good. Details are preserved.
Content at the TVs native 1080p resolution looks good. No issues can be seen.
Standard color gamut, but good enough for SDR content using the Rec 709 color space.
Poor color volume. The TV's standard color gamut and low contrast ratio prevent it from showing a lot of colors at a range of brightness levels.
The LG LJ5500 performs excellent on our gradient test. Almost no banding at all can be seen on our test picture, besides some little irregularities in the dark green. No 8-bit banding can be seen at all. This is one of the best gradients with have tested yet in 2017.
The LG LJ5500 IPS TV does present some image retention. After the 10 minutes burn-in scene, as we can see on our test picture, the image retention is easily noticeable, but after 2 minutes of recovery, the retention is already very faint and almost non-noticeable.
Even if this result is disappointing, overall, when you compare to other TV, VA panel TVs especially, the fact that the retention clears up pretty fast is good news and when compared to other IPS TVs tested before, the LJ5500 would be in the middle of the group performance wise.
Although some IPS panels can suffer from temporary image retention, this doesn't appear to be permanent as seen in our long-term test.
The LG LJ5500 uses PWM at 120Hz to dim the backlight, starting at 100/100 backlight setting. Lowering the setting shortens the duty cycle, while amplitude remains constant. Backlight PWM helps clear up motion slightly, but results in duplicate images following fast-moving objects, visible in the motion blur picture.
The LJ5500 has no optional BFI setting to reduce its flicker frequency to 60 Hz, though its 120 Hz PWM backlight does help somewhat to make motion more clear.
The LJ5500 has no motion interpolation features, so fans of the soap opera effect may be disappointed.
The LJ5500 is great at displaying movies and sports without any stutter. The LCD response time helps to blur the transition between frames, producing smooth movement even for movies.
The LJ5500 can display without judder 24p movies only from 24 sources and this when the 'Real Cinema' option (from the 'Picture Option' menu). 24p movies playing from 60p/60i sources do present some judder, and unfortunately, there is no way to remove it.
The LG LJ5500 has a 60Hz panel without support for more advanced features such as FreeSync.
Great low input lag, which should please all but the most competitive gamers. The 'Game' picture mode has the lowest input lag, even in PC mode. PC mode on most other LG TVs has low input lag for all picture modes, but this is not the case with this TV, as only the Game picture mode has low input lag.
Because this TV only has a 1080p @ 60 Hz panel, many common resolutions aren't supported. 4:4:4 color is only shown properly when the input's icon is set to PC (aka 'PC mode').
Disappointing frequency response. While the LJ5500 follows the target very well, its limited low-frequency extension makes it sound quite thin. It also has a fair amount of dynamic range compression at higher volumes, and it doesn't get very loud at all.
Good distortion performance. While there is a rise in IMD at higher volumes, the levels are low throughout. THD also remains low at max volume which is unusual.
